SOFA-BED.

4andy particularly that typel in which the front portion of the back may be swung forward and downward at the top to give access to the storage space.

Sofa beds have been' made heretofore in which the swinging member of the back is connected permanently l to the rigid portion by links depending from stationaryy pivots fixed therein. 'It is desirable, in order to fa'- cilitate packing, shipping, and assembling ysofa beds, that a knock-down form ofconstruction be used throughout as far as prac-` ticable, and means have been devised Vheretofore for making the seat demountable with respect to thev sofa frame and also means f for making the sofa'back detachable from the frame ends. l

The main objects lofthis invention are to provide an improved form. of hollow sofa back having a* swinging front portion, and to provide improved means for mounting the swinging portion whereby it shall be readily demountablev with respect to the stationary portion or main framework of the back, and whereby in swinging tol and from.

its folded position it Vshall clear the seat member, especially where the latter is upholstered and projects rearward closely Vbeneath the swinging back; to provide coacting pivot and slot means of simple character for mounting the swinging back adjacent to its base and adapted to carry the lower portion thereof in such manner that its lower front corner shall clear the seat as the top portion swings forward and downward in opening; and to provide improved stop means for limiting the forward swing of the movable back member.

Illustrative embodiments o f this invention, including certain modifications are Specification of Letters Patent.

Fi 2 isy a vertical cross section on the* line -B of Fig.'1, and shows an endview of the sofa bedwith the nearv end of the frame removed, the swinging back being in its normal position.

Fig. 3 is like Fig. 2 except that the lower portion is broken away and the swinging backis' tilted forward. v i

Fig. 4 is a fragmentary longitudinal section on the line C--C of Fig. 2.

Fig. 5 is a cross-section of the back in its normal position and showing a double slot and stud construction for the mounting plates.

Fig.` 6 is similar to Fig.' 5 except that the back is swung forward..

inner sidey view of the and 6, in thefposition In the construction shownin the draw- 'y ings, the sofa bed comprisesa frame 1, hav

ing ends 2 connected by the stationary portion 3 of the back, a seat 4 and a swinging back member 5 formedto serve as a storage receptacle for bedding. Said seat may beV of any desired type, preferably rotary, with a foldable bed bottom 6 carried on its under slots in thev plate` back. With this object in view, 'the slot is formed to throw the plat/e upwardly and forwardly with respect to said pivot 13 in swinging the back forward, said slot as a whole having a forward and upward inclination and preferahlyvbeing nearly vertical atv its lower end and curved forwardly at its upper end, though the precise form of the slot may be varied. An aperture 15 is provided in the lower rim or concave side of said slot for the passage of said pivot into and out of said ,slot in mounting and demounting said hack 5. Said pivot 13 is headed and said slot 12 is correspondingly flanged toretain said pivot. Stop means are Aprovided for arresting Athe opening or forward swinging of said back 5. in this instancethe vertical corner post 17 of the. sofa frame is provided with a notch 18 to receive the lower rear corner 19 of the swinging backas it moves upward in opening, said corner sliding into said notch and thereby arresting the swinging. The stop means, if desired, may' be made selective, for which purpose a plurality of notches may be provided, as indicated by the dotted line at 22 in Fig. 2, whereby the degree of opening may be adjusted at will. In case a plurality of notches are used, the back may be prevented from engaging the lower notch by lifting somewhat on the back as it swings forward to its widest position.

Referring to Figs. 5, 6, and 7', the back 5 at each end is mounted plates 50 and 51 fixed to the adjacent end v2 and back 5 respectively. The coactive support means of each pair of plates comprise two studs or pins 54 and 55, one of which, 54, acts normally as a stationary pivot, and the other moves in an arc concentric therewith, andI two guide slots 57 and 58 for said studs respectively, said slots being formed open at one end to facilitate mounting and demounting the back 5. 1n this instance the studs are both carried by the stationary plate 50 and the slots are both formed in the back plate 51, said slots both terminating at the front edge of said plate 51 where they are open ended.,

The lower slot 57 turns downward immediately from its opening and terminates as a socket or center bearing for the forward -tends to so hold it. Said swinging back is to swing on a pair of' pivot 54. The upper slot 58 likewise turns downwardfrom its opening for a like distance, and thence turns backward and downward in an are concentric with the lower end of slot 57, said arc being preferably about 60 corresponding to the angular opening of the back when swung forward. Said slots and studs may be flanged and headed respectively as shown. When the back 5 is swung forward the stud 55 slides in slot 58 and is arrested by the shoulder 6() adjacent to the open end of said slot. The back 5 may be removed when open by lifting the sameso as to canse the studs 54 and 55 to slide upward and forward out of their slots.

rhe operation of the device of this invention is as follows: The swinging `back is opened by grasping the upper edgeand pulling the same forward until said back is arrested by the stop provided therefor. When the device is in its open position it is so held by gravity, and when closed. gravity likewise closed merely by lifting on the forward or upper edge and swinging it back to its normal position. Said swinging hack may be operated when the seat is in either its normal sofa position or in its inverted position. l

1t is to be understood that some of the details shown may be altered or omitted withont departing from the spirit of this invention as delined by the following claim.

In a sofa bed, a frame having ends spaced apart and a swinging hollow back carried pivotally by and between said ends, in comhination with mounting means at each end of said back comprising a pair of plates,one fixed to the adjacent end of the frame and the other fixed to the adjacent end of said back adjacent to its bottom,the movable plate having a pair of pivot-like studs spaced apart and facing outward, and the stationary plate having a pair of slots therein extending forward one over the other and each open ended at its front end, the lower slot turning downward and terminating, and the upper siot turning down and thence lying in an arc concentric with the inner -end of the lower slot and spaced therefrom according to the spacing of said studs, saidstuds coacting with said slots respectively.
